Abstract
The invention is a process of degassing and cooling a hot black water slurry. The hot black water slurry is obtained from syngas scrubbers. The black water slurry is cooled and degassed by exposing the black water slurry to a vacuum under conditions sufficient to separate dissolved gases from the black water slurry. These gases are then removed from the black water slurry. These gases can advantageously be recycled in the gasification process.
